If any straight line parallel to `X` -axis intersects the graph of the function at most at one point then the function is

Given the graphs of the two functions, y= f(x) & y =g(x). In theadjacent figure from point A on the graph of the function y fx)corresponding to the given value of the independent variable (say x),a straight line is drawn parallel to the X-axis to intersect the bisectorof the first and the third quadrants at point B. From the point B astraight line parallel to the Y-axis is drawn to intersect the graph ofthe function y= g(x) at C. Again a straight line is drawn from the point C parallel to the X-axis, to intersect the line NN' at D. If thestraight line NN' is parallel to Y-axis, then the co-ordinates of the point D are

A horizontal line meets the graph of the function y=f(x) in two points is f one one?

Graph of function: Vertical line test

If the graph of the function y=f(x) is symmetrical about the line x=2, then

The graph of a thermodynamic process is a straight line parallel to pressure axis in P - V diagram. What is the work done in that process ?

A line is parallel to X-axis,if all the points on the line have equal………..

The angle between the tangent lines to the graph of the function f(x)=int_(2)^(x)(2t-5)dt at the points where the graph cuts the x-axis is
